Replace pkg_resources with importlib_metadata

[jbylund]

Copying description from issue:

pkg_resources is now deprecated in favor of importlib.metadata / importlib_metadata (source). Right now it causes warnings and in the future (3.12?) I think it will stop working entirely. I saw there was a related pr but it was using importlib.metadata which apparently has different behaviors on some versions of python and caused issues for some users (ref). Maybe it would be acceptable to use importlib_metadata (the backport) either on all versions of python or only when necessary.

Thanks for spotting that!

I would be ready to accept this PR, but the pre-commit hook isort is failing due to the non-standard ordering of imports. Please see CONTRIBUTING.md for more details.

I'm a little worried about the use case of #244 (using without installing via just adding to path). But it seems to work for me:

In [5]: import arango

In [6]: arango.__file__
Out[6]: '/Users/joebylund/scratch/python-arango/arango/__init__.py'

In [7]: ArangoClient().version
Out[7]: '7.5.8.dev2+gfac52f3'

That's a valid concern, I'll have to test it out as well. Will get to it by the end of this week.

I tried it locally as well and it works for me. However, I am hesitant to merge it yet, without @alexbakharew 's input, as this can potentially affect some of our internal projects.

Alright, I talked to @alexbakharew and he confirmed it's working.
Thank you for your contribution!
